BACKGROUND

1. Field of Invention

The present invention relates generally to lawn and garden sprayers.

2. Background of Art

Lawn or garden sprayers use pressure to apply liquid fertilizers,pesticides, or other chemicals. A recent development is to utilize abattery-powered electric motor in the sprayer wand to provide thespraying pressure, rather than hand pumping.

For present-day sprayers packaged at point of sale, the wand and itshose are stored separately from the sealed container and held in aseparate “holster” carry device that is attached to the container, withthe wand pointing up. Once the wand and hose are unpackaged andassembled for use, the holster may then be used for continued carry andstorage of the wand. The holster uses tabs and knobs to reattach thewand, which is cumbersome for the user, and as a result does not holdthe wand and hose as securely as originally packaged.

The hose is typically connected to the container by sliding the hose endplug onto the horizontally positioned spout on the container cap. Inthis position the spout mechanism is designed such that the container issealed. To use the sprayer, the spout must be rotated from thehorizontal to the vertical position. With the spout in the up position,the fluid circuit to the wand is opened. Simultaneously, a small openport in the cap under the spout is exposed which permits air to enterthe container; without this air port the fluid would not flow. Forstorage, the spout can be repositioned horizontally, in order for thespout mechanism to seal the container.

For contemporary battery-powered wand sprayers, the batteries, electricmotor, pump mechanism, and related electrical and fluid circuits arehoused in the wand handle. A user-operated trigger functions to actuatethe motor and to simultaneously allow fluid to flow to the pump. Fluidflow to the pump is controlled by a valve body that is separate from themotor housing. Having the valve body separate from the motor housingadds complexity to the design.

OBJECTS AND ADVANTAGES

It is a principal object and advantage of the present invention toprovide a sprayer that enables improved ease of operation and increasedfunctional efficiency.

Other objects and advantages of the present invention will in partappear hereinafter and in part be obvious.

DETAILED DESCRIPTION

Referring now to the drawings wherein like reference numerals refer tolike parts throughout, there is seen in FIGS. 1 and 2 a sprayer systemdesignated generally by reference numeral 10 essentially comprisingcontainer 12 and spray wand 14 fluidly connected to container 12 byflexible hose 16. More specifically, flexible hose 16 extends betweenwand 14 and a cap 18 positioned on top of container 12.

Spray wand 14 comprises a handle/wand housing 20 and wand portion 22that is telescopically attached to handle 20 for sliding movementbetween stored (non-operational) and extended (operational) positions. Alug 24 is formed on the rear wall of container 12 and provides amounting point for spray wand 20. Handle 20 includes a slot 26 formedtherein that is sized and shaped to securely slidingly engage lug 24from the top, thereby permitting spray wand 14 to be stored on container12 with wand portion 22 facing downward during shipment/display and whennot in use and stored away. Having the wand portion 22 pointing downprevents liquid from falling back into the wand when it is being stored.

Referring to FIGS. 3-5, another feature associated with container 12 isa communication card assembly 28 that attaches to lug 24 and ispositioned between container 12 and spray wand 14 when the sprayersystem is shipped and displayed for sale. Communication card assembly 28comprises a card retaining portion 30 to which a card 31 may be adheredor otherwise attached and an assembly attachment portion 32 andfunctions to communicate product information to the consumer; containthe wand 14 and coiled hose 16; and provides security to the packaging.Card assembly 28 may be released from container 12 by tearing alongperforation lines 34 and then discarded or recycled by the customerduring the connection of the hose 16 to the container 12. FIG. 4 simplyrepresents a refill container 12 that can be supplied/sold without thewand assembly 14 which is facilitated due to the use of lug 24 and slot26 that permits reuse of the wand assembly 14.

To retain wand 14 and coiled hose 16, card assembly 28 includes lockingmechanism 36 that engages slot 26 and prevents detachment of the wanduntil the card assembly is detached from container 12 via perforationlines 34.

With reference to FIGS. 6A-6C and 7A-7C, container 12 includes a cap 18that is shipped with a safety seal 40 adhered there over. Upon removalof safety cap 40 and detachment of wand 14 and hose 16 from thecontainer 12, the coupler end 42 of hose 16 may be snappingly engagedwith an exposed opening 44 on cap 38. Coupler 42 includes a pair ofopposed, biased latches 46, 48 extending downwardly therefrom thatsnappingly and securely engage a flanged rim 50 formed on the undersideof cap 18 to secure hose 16 to container 14, and create a fluid circuitbetween the fluid contents within container 12 and wand 14, as will bedescribed hereinafter. Once connected, coupler 42 is capable ofswiveling 360 degrees relative to cap 18.

With reference to FIGS. 8-11, there are four versions or configurationsin which the hose 16 establishes a fluid circuit with the fluid contentsof container 12. In the first version shown in FIGS. 8A and 8B, coupler42 includes a separate stem 52 that extends downwardly from the coupler42 and through cap 18. In this version both the necessary air and fluidsealing is controlled by a spring loaded plunger 54 that is positionedalong the longitudinal axis X-X that extends centrally through the cap40 and is separated from stem 52 by a spring 56 that is coaxiallysandwiched between a dip tube holder 57 (that holds/retains dip tube 59)and plunger 54. In FIG. 8A which shows the coupler 42 disconnected fromthe cap 18, spring 56 biases plunger 54 upwardly which annularly sealsthe fluid circuit at point 58 and annularly seals the air passage atpoint 60. In FIG. 8B which shows coupler 42 connected to cap 18, stem 52engages and compresses spring 56, thereby opening a fluid passageway asreflected by arrow 62 as well as an air passageway as reflected by arrow64. The simultaneous opening of passageways 62 and 64 permits the flowof fluid out of container 38 (when the trigger on the wand is manuallyactivated and compressed air is present within container 38 asunderstood in the art).

With reference to FIGS. 9A and 9B, a second version or configuration inwhich hose 16 establishes a fluid circuit with the fluid contents ofcontainer 18 is shown. In FIG. 9A, an umbrella valve 66 is positioned insealed relation to an air passageway located at the bottom of cap 18. Asshown in FIG. 9B, when the stem 52 engages and compresses spring 56 itdisplaces the plunger 54 which in turn causes the fluid passageway 62(same as first configuration) to open and also causes umbrella valve 66to pop and open air passageway 68. The simultaneous opening ofpassageways 62 and 68 permits the flow of fluid out of container 18(when the trigger on the wand is manually activated and compressed airis present within container 38 as understood in the art).

With reference to FIGS. 10A and 10B, a third version or configuration inwhich hose 16 establishes a fluid circuit with the fluid contents ofcontainer 12 is shown. In this configuration, everything is identical tothe first version except that stem 52 is integral with coupler 42instead of separate as it is with the first version. Otherwise, thisthird version and the first version are identical.

With reference to FIGS. 11A and 11B, a fourth version or configurationin which hose 16 establishes a fluid circuit with the fluid contents ofcontainer 38 is shown. In this configuration everything is identical tothe second version except that stem 52 is integral with coupler 42instead of separate as is with the second version. Otherwise, thisfourth version and the second version are identical.

With reference to FIGS. 12A and 12B, an aspect of the present inventionis shown that includes integration of a valve body into a pump/motorhousing. In this aspect of the invention, a wand handle 100 includes ahollow interior volume in which a motor 102 is stowed. Integrated withmotor 102 is a valve body 104 that is operational between open andclosed positions by means of a trigger 106 mounted on the underside ofthe handle 100. The wand 108 is pivotally mounted to handle 100 and influid communication with a fluid outlet 110 that extends from valve body104. A fluid inlet 112 is placed in fluid communication with the fluidcontents of container 38 (not shown in these figures) by means of a diptube, such as dip tube 59 shown in other Figures. Upon manual movementof trigger 106, the fluid passageway between inlet 112 and outlet 110 isopened and upon release of the trigger the passageway is closed, therebyfluidly sealing container 38. The use of a motor to drive a pump andprovide the pumping necessary to compress and expel fluid from acontainer is otherwise well understood in the art.
